    We are designing a product with varying power requirements. It will be powered from the USB bus. The product will use a USB 2.0 compliant PIC microprocessor however would benefit from the 900mA which USB 3.0 ports can offer, rather than be restricted to the 500mA of USB 2.0. We will use a USB-C connector. We need identification of components and circuit design to achieve this.
